Driggs to Scottsbluff Road Trip: Wyoming Plains Guide

On U.S. Route 26 east of Driggs, Idaho, the Teton Range vanishes in the rearview mirror as you cross into Wyoming near Teton Pass. This 650-mile journey to Scottsbluff, Nebraska, follows the Oregon-Mormon Pioneer Trail corridor for much of its length.

• Total distance: 650 miles (1,046 km)
• Estimated drive time: 10–11 hours without stops
• Highways: US-26, US-287, US-20, I-25, US-26 again
• Key towns: Jackson, Riverton, Casper, Douglas, Torrington

The route crosses three mountain passes, the Wind River Basin, and the high plains. It is how to find the best stops and hidden gems between cities a classic American transect—from alpine peaks to shortgrass prairie.

Fuel stations are concentrated in towns; between them, stretches can exceed 80 miles without services. The longest gap is between Riverton and Casper along US-20/US-26—about 120 miles with only the tiny town of Waltman offering gas.

• In Driggs, fill up at Sinclair or Chevron before heading over Teton Pass (elevation 8,431 ft).
• Jackson has multiple stations, but prices are higher due to tourism.
• Riverton and Casper serve as major refueling hubs with competitive prices.
• Scottsbluff has several stations; exit US-26 at Avenue I for best options.

Cell service is intermittent, especially from Teton Pass through the Bridger-Teton National Forest and along US-20/US-287 between Rawlins and Muddy Gap. Download offline maps in advance.

Road Quality

US-26 from Driggs to Moran is winding two-lane with frequent frost heaves. US-20/US-287 across Wyoming is well-maintained but narrow in places. I-25 from Casper to Douglas is excellent divided highway. US-26 east of Douglas becomes two-lane again with moderate shoulder width.

The drive begins in the Caribou-Targhee National Forest, with lodgepole pine and aspen groves. After cresting Teton Pass, the valley opens to the Jackson Hole valley, with the Teton Range dominating the western horizon.

• Bridger-Teton National Forest: elk, moose, occasional black bear near the road.
• Wind River Canyon (US-20 between Shoshoni and Thermopolis): dramatic limestone cliffs, river rafting.
• Painted Hills at Red Desert: hued layers of claystone visible from US-287.

Commerce along the route reflects Western heritage. Jackson is upscale, with galleries and outfitters. Riverton offers a working ranching economy—local feed stores, farm equipment dealers. Casper has oil and gas influence. Scottsbluff is agricultural, with sugar beet processing and irrigation featuring prominently.

UNESCO World Heritage Sites

The route passes two UNESCO-designated sites. The first is the Yellowstone National Park entrance at West Thumb (a detour 60 miles north of Jackson). The second is the Indigenous-related sites of the Wind River Indian Reservation, specifically the Medicine Wheel/Medicine Mountain (near Lovell, a detour from Thermopolis). Both are designated for their cultural and natural significance.

The greatest hazard is wildlife collisions, especially at dawn/dusk between Driggs and Moran, and along the Wind River Canyon. Antelope and mule deer are common; elk and moose are less frequent but more dangerous.

• Weather: Snow possible from October to May; summer thunderstorms with hail.
• Road surfaces: US-26 east of Shoshoni has sunken patches due to thermal cracking.
• Emergency services: Casper is the best location for major vehicle repair; otherwise, towing to Riverton or Jackson may be needed.

Family-friendly stops include the National Museum of Military Vehicles near Dubois (US-26), the Fort Caspar Museum in Casper (free admission, interactive exhibits), and the Scotts Bluff National Monument visitor center (junior ranger program available). Pet-friendly framework: most rest areas have designated pet walks; national forests permit dogs on leash. Avoid leaving pets in hot cars at scenic pullouts.

Fatigue Management & Rest Zones

Fatigue is a real risk on the long, straight stretches of US-20/US-26 across the Wyoming plains. The Wyoming Department of Transportation has rest areas at approximately 60-mile intervals: one just west of Dubois, another near Waltman, and one east of Casper. On I-25, rest stops are at 50-mile intervals.

• Best stop for a break: Sweetwater Station rest area (US-287) has shade trees and picnic tables.
• Alternative: McDonald's in Douglas (20-minute stop recommended).
• Plan to stop every 2 hours for at least 15 minutes.
